We extend Lazear's theory of skills variety and entrepreneurship in three directions. First, we provide a theoretical framework linking new business creation with an entrepreneur's skill variety. Second, in this model we allow for both generalists and specialists to possess skill variety. Third,...

Building on a Lewis-type model of structural change and entrepreneurship we show how a global economic crisis consisting of a financial and a trade shock can undermine structural change in developing countries via the start-up and innovation activities of entrepreneurs. The model analytics...

Rapid technological progress in artificial intelligence (AI) has been predicted to lead to mass unemployment, rising inequality, and higher productivity growth through automation. In this paper we critically re-assess these predictions by (i) surveying the recent literature and (ii)...

A stylized fact of economic development is the structural transformation of countries from traditional, mainly agricultural societies to modern economies dominated by manufacturing and services. In this paper we provide an endogenous growth model to illuminate the role of entrepreneurial...

Start-ups of new firms are important for economic growth. However, start-up rates differ significantly between countries and within regions of the same country. A large empirical literature studies the reasons for this and attempts to identify the regional determinants of start-ups. In contrast,...

The success of new start-up firms often depends on timing. It is valuable for the potential entrepreneur to wait for the right moment before starting a new firm. In this paper we provide a theoretical model to determine the optimal time for starting a new firm. We integrate insights from the...

Success in international trade depends, amongst other things, on distance from markets. Most new economic geography models focus on the distance between countries. In contrast much less theorizing and empirical analysis have focused on how distances within a country for instance due to the...

We propose that the rate of creation and failure of start-up firms can be modelled as a search and matching process, following labor market matching models. Setting out an endogenous growth model with entrepreneurship we derive a Entrepreneurship Beveridge Curve, through which we illustrate that...

The economic impact of Artificial Intelligence (AI) is studied using a (semi) endogenous growth model with two novel features. First, the task approach from labor economics is reformulated and integrated into a growth model. Second, the standard represen- tative household assumption is rejected,...
